Severity: High Title: Heimdal: ftpd root escalation Date: September 16, 2004 Bugs: #61412 ID: 200409-19

Synopsis ========
Several bugs exist in the Heimdal ftp daemon which could allow a remote attacker to gain root privileges.
Background ==========
Heimdal is an implementation of Kerberos 5.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/heimdal < 0.6.3 >= 0.6.3
Description ===========
Przemyslaw Frasunek discovered several flaws in lukemftpd, which also apply to Heimdal ftpd's out-of-band signal handling code.
Additionally, a potential vulnerability that could lead to Denial of Service by the Key Distribution Center (KDC) has been fixed in this version.
Impact ======
A remote attacker could be able to run arbitrary code with escalated privileges, which can result in a total compromise of the server.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Heimdal users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=app-crypt/heimdal-0.6.3" # emerge ">=app-crypt/heimdal-0.6.3"
